    Abstract: A CMOS integrated circuit has NMOS and PMOS transistors therein and an insulating layer extending on the NMOS transistors. The insulating layer is provided to impart a relatively large tensile stress to the NMOS transistors. In particular, the insulating layer is formed to have a sufficiently high internal stress characteristic that imparts a tensile stress in a range from about 2 gigapascals (2 GPa) to about 4 gigapascals (4 GPa) in the channel regions of the NMOS transistors.

    Abstract: Copper-based metallization is formed in a trench on an integrated circuit substrate by forming a liner of refractory metal in the trench using physical vapor deposition, forming a copper plating seed layer on the liner using physical vapor deposition and then plating copper on the copper plating seed layer. Prior to plating copper on the copper plating seed layer, the liner and/or copper plating seed layer is stuffed with hydrogen, for example by exposing the liner and/or copper plating seed layer to a hydrogen-containing plasma during and/or after formation of the liner and/or copper plating seed layer. Related structures also are disclosed.

    Abstract: A method of forming a via contact structure using a dual damascene process is disclosed. According to one embodiment a sacrificial layer is formed on an insulating interlayer during the formation of a preliminary via hole. The sacrificial layer has the same composition as a layer filling the preliminary via hole in a subsequent trench formation process. The sacrificial layer and the layer filling the preliminary via hole are simultaneously removed after the trench formation process is carried out. According to another embodiment, a thin capping oxide layer is formed on an insulating interlayer during the formation of a preliminary via hole. The thin capping oxide layer is removed together with a sacrificial layer after a trench formation process is carried out.

    Abstract: Provided are a dual damascene interconnection with a metal-insulator-metal (MIM) capacitor and a method of fabricating the same. In this structure, an MIM capacitor is formed on a via-level IMD. After the via-level IMD is formed, while an alignment key used for patterning the MIM capacitor is being formed, a via hole is formed to connect a lower electrode of the MIM capacitor and an interconnection disposed under the via-level IMD. Also, an upper electrode of the MIM capacitor is directly connected to an upper metal interconnection during a dual damascene process.
